This study presents computational results in a complex three-dimensional louver geometry. The threedimensionality
occurs along the height of the fin, where the angled louver transitions to the flat landing and joins
with ...

The effects of condensation on the air-side performance of plate-fin-tube heat
exchangers have been experimentally investigated by conducting experiments under dry
conditions and then repeating these experiments under ...

Yin, J.; Jacobi, A.M.(Air Conditioning and Refrigeration Center. College of Engineering. University of Illinois at Urbana-Champaign., 2000-01)

The effect of condensation on air-side heat transfer performance has been studied
for plain-fin-and-tube and wavy-louvered heat exchangers with fin spacings of 2.12, 1.57,
and 1.27 mm. Wet and dry heat exchanger experiments ...
